Paste dispensing tube



Patented June 14, 1932 UNITED STATES JAMES A. TISCORNIA, 0F SAN JOSE,CALIFORNIA PASTE DISPENSIN G TUBE Application led November 12, 1930.Serial No. 495,097.

This invention relates particularly to that type of tube used for toothpaste, shaving cream, etc.

It is one object of the invent-ion to provlde means whereby the contentsof the tube may be forcibly spread upon the surface to which it isapplied immediately upon its discharge from the tube.

It is another object of the invention to provide means of the characterindicated that forms an integral part of the tube closure so as topractically eliminate the chances of its being misplaced.

It is still another object to provide a combination closure-applicatorthat will function without removing any part from the tube and that isself cleaning and sanitary.

It is also an object of the invention to pro vide a device of thecharacter indicated that will be economical to manufacture, of fewparts, simple in form and construction, and highly eicient in itspractical application.

In the drawing:

Figure l is a plan View of one form of my invention in position upon atube.

Figure 2 isa side elevation of the same.

Figure 3 is another side elevation of the same, part broken away.

Figure 4 is an end elevation of another emboliment ofthe invention inposition on a tu e.

Referring now more particularly to the particular form of the inventionherein disclosed, I show at l a portion of a collapsible tube having acap 2 mounted thereon in the usual manner.

The cap 2 has an oblong plate-like portion as 3 formed upon its outerend, this plate presenting an outwardly directed spreader surface as 4lying in a plane disposed at right angles to the long axis of the tube.This cap has a discharge passage, 5 formed therethrough on the axis ofthe tube, and has a transversely disposed slot 6 extending therethroughand intersecting the passage 5.

In the slot 6 is mounted a slide 7 having a hook-like end 8 adapted toengage the edge of plate 3 as at 9, in which position the slidefunctions as a closure for the passage 5. To open the passage pressureis brought to bear against end 10 of the slide thereby -disengaging end8 from plate 3 and moving the orifice 11 in slide 7 into registrationwith passage 5. With the slide in this latter position the contents of'theitube -may be discharged inthe usual manner.

It is obvious from the foregoing disclosure that when the slide is inthe position shown in Figure 3 the tube is perfectly sealed, and theslide is held against accidental displacement. When it is desired to usesome of the paste upon a tooth brush it is only necessary to operate theslide as above set forth whereupon the required amount of paste may besqueezed out. By pressing the plate 3 against the brush and sliding italong on the same as the paste is discharged, the paste is spread uponthe brush and pressed between the bristles in such a manner that it iseffectually retained in place until used. An important feature of' thisinvention is that the discharge passage is opened and closed by merelysliding the part 7 in the desired direction, no part being removed fromthe tube to effect the opening of the passage.

By means of this construction the tube is sealed at its very end, andthe movement of the spreader over the brush at right angles to thedirection of movement of the slide renders it self cleaning and preventsaccumulation of paste upon the slide and the parts touched by thefingers.

In the embodiment of the invention shown l in Figure 4 the face of thespreader is curvihuear 1n transverse cross sectlon to form a channel as12 through which the brush, shown in part at 13, is drawn, the curvingsides effectually prevent-ing lateral displacement of' the cream on thebrush even when but little .pressure is applied in depositing the creamon the brush.

It is to be understood, of course, that while I have herein shownanddescribed but one specific embodiment of the invention, changes.

1n form, construction, and method'of assembly and operation may be madewithin the scope of theappended claim.

I claim:

A spreader head for collapsible paste tubes comprising, an elongatedelement disposed on 2 Lseaevo the cud of the tube crosswise thereof andprovided With an outwardly directed spreader surface curvilinear intransverse cross-section and having a passage formed therein.Communicating with said surface and the interior of the tube, the saidelement having a slot formed therethrough crosswise thereof andintersecting said passage, and an element slidably mounted in said slotand having an orifice formed therein registrable With said passage.

JAMES A. TSCORNA.'
